AbstractPenicilliumspp. are well known to produce a variety of beneficial metabolites for plant growth and survival, as well as defend their hosts from attack of certain pathogens. In this study, effects of culture filtrate of differentPenicilliumspp. were tested on tomato seeds. On the whole, presoaking of seeds in filtrates of the ninePenicilliumisolates tested, significantly increased seed germination when compared with the control seeds. Cultural extracts ofP. expensumandP. billiwere highly effective in growth promotion up to 90%. It was also observed thatP. implicatumandP. oxlalicamsignificantly enhanced the root growth in tomato seedling as compare to other species. In case of shoot length,P. verrucosum(3.38),P. granulatum(2.81) andP. implicatum(2.62) were effective. HoweverP. implicatumwas quite promising to increase shoot and root length in tomato seedlings. Where asP. simplicissimiumandP. citrinumwere leas effective on seedling growth. The plant growth promoting ability ofPenicilliumstrains may help in growth permotion in other plants and crops.Penicilliumspp. are already known for producing mycotoxin and enzymes. Plant growth promoting ability ofPenicilliumspp will open new aspects of research and investigations. The role ofPenicil-liumspp. in tomato plant growth requires further exploration.

Different Doses

Growth-promoting rhizobacteria are soil bacteria that inhabit the surrounding root, and are directly or indirectly involved in promoting plant growth and development. The productivity efficiency of these groups of microorganisms can be applied to planting crops, providing an interesting alternative for minimize the negative effects of water deficit. The objective of this study was to verify if the mechanism of growth promotion of the bacterium is similar to that promoted by polyethylene glycol (PEG) and to compare the possible effects of water stress on the tomato against the effects of inoculation of the bacterium Serratia sp. The methodology was based on in vitro bioassays using tomato (Solanum lycopersicum L.) seedlings, kept in a growth chamber with temperature of 25 °C and photoperiod of 12 hours. The results revealed that the promotion of tomato root growth by Serratia sp. is similar to that promoted by PEG 7%, differing significantly from the results found with different doses of indoleacetic acid (IAA). The promotion of root growth in tomatoes by Serratia sp. and PEG 7% partly indicates a physical effect, since the water restriction imposed by the PEG molecule decreases the water movement capacity, also observed by bacteria, when colonizing plant tissues and cells (biofilm) reducing the hydraulic conductivity of water through the root. Stimulation to promote root growth in tomatoes cannot be reproduced by auxin.

Planting Methods

In this study we evaluated the effects of two different types of mulches (black mulch, silver/black) on weed control and yield in tomato (Solanum lycopersicum L.) production. Field studies were carried out during 2017-2018 and 2018-2019. The treatments consisted in the study were planting methods (raised bed/flat bed), polythene mulching applications (black mulch, silver/black and unmulched plots) and training systems (two stem and three stem). Tomato seedlings were transplanted in the plots, where mulch application had already been done prior transplanting.The results indicated thatmarketable tomato yield from the treatments consisting of black mulch, was higher compared to the other unmulched plots for both the years of study. In unmulched plots there was reduction of tomato yield. Mulch treatments reduced the number of weeds, weed intensity, and above ground biomass (fresh weight and dry weight of weeds) as compared to control plots. At tomato harvest weeds were well suppressed by black mulch above the entire where black mulches have been used. In mulch plots there was consistent reduction in weed intensity also. The black mulch seems to be a suitable for assuring an effective weed suppression and high yield in tomato grown in raised beds compared to the plants grown on flat beds without using any mulch material.
